Title: Magnetic recording medium
Inventor: HAGA SHUICHI
IPC: G11B5/64
Filed: 1991-03-01
Abstract: PURPOSE:To obtain a magnetic recording medium excellent in running property and durability by interposing a middle layer contg. a coupling agent between a protective film and a lubricant layer formed on a nonmagnetic substrate. CONSTITUTION:A magnetic layer 4, a protective film 5, a middle layer 6 contg. a coupling agent and a lubricant layer 7 are successively formed on a nonmagnetic substrate 1. Tight bond is attained between the protective film 5 and the lubricant layer 7 by the action of the coupling agent in the middle layer 6 and satisfactory adhesive strength of the layer 7 to the film 5 can be ensured. As a result, the reduction of the thickness of the lubricant layer 7 by migration and evaporation due to heat can be inhibited and satisfactory running property and durability can be obtd.

Title: Interval detection method and manufacture of semiconductor device using the same
Inventor: NOSE TETSUSHI
IPC: G03F9/00
Filed: 1992-02-14
Abstract: PURPOSE:To detect the face interval between a first object and a second object by a method wherein a first light flux and a second light flux are made obliquely incident on the second object, they are condensed and polarized, a third light flux and a fourth light flux are made obliquely incident on the second object, they are radiated and polarized and the interval between incident positions of the first and second light fluxes and the interval between incident positions of the third and fourth light fluxes are used. CONSTITUTION:Two measuring systems are installed in such a way that they are in a symmetrically turned-down relationship with respect to an optical axis 79. As a result, when a wafer 73 is situated in a position 731, the interval between a mask 72 and the wafer 73 generates two light spots 801 on a sensor face 77 symmetrically with respect to the optical axis 79 in positions which are away by a distance y1 from the optical axis 79. The spot interval between the light spots 801 formed on the sensor face 77 and light spots which are symmetric with respect to the optical axis 79 gives the face interval d1 between the mask 72 and the wafer 73. The absolute value of the face interval between the mask 72 and the wafer 73 which have been counterposed in this manner can be detected with high accuracy by a simple constitution and without calibrating the absolute value.

Title: Control device for water quality of cooling system using nitrous acid rust preventive material
Inventor: MAEDA KATSUHARU
IPC: C23F11/18
Filed: 1984-03-28
Abstract: PURPOSE:To control automatically the quality of cooling water in a cooling water system using a nitrous acid rust preventive material by monitoring automatically and continuously the concn. of the nitrate ion in the cooling water and replenishing automatically the blow of the cooling water and the nitrous acid rust preventive material according to need. CONSTITUTION:An NO2 rust preventive material is added to cooling water used for coolers of various apparatus to prevent the corrision thereof. If NO2 ion changes to NO3 ion, the corrosiveness increases conversely and therefore an electrical conductivity meter 3 and an NO2 ion analyzer 4 are attached to the circulating system of a cooling water system 1 contg. NO2 ion and the measured values thereof are inputted to a calculator 5 by which the concn. of the NO3 ion in the cooling water is calculated and determined. A blow valve 6 is opened according to the concn. value of the NO3 ion to release part of the cooling water having a high concn. of NO3 and at the same time a rust preventive material feed pump 14 is operated to feed a rust preventive material 13 having a high concn. of NO2 ion in the tank to the circulating system for the cooling water. The deficient amt. of water is replenished from a tank 9. The NO2 ion in the cooling water is increased and the NO3 ion is decreased by which the rust preventive performance is recovered.

Title: Fuel filter for automobile
Inventor: ITSUSHIKI NORIO
IPC: B01D61/18
Filed: 1982-04-10
Abstract: PURPOSE:To remove moisture in fuel, by using a ethyleneterephthalate resin porous membrane as a fuel filter for an automobile. CONSTITUTION:A ethyleneterephthalate resin porous membrane filter 6 is provided in a fuel tank 1 having a fuel supply port 5 so as to partition the space of said tank 1. Fuel stored in the tank 1 is permeated through the porous membrane filter 6 to be sent to a usual filter 2 and a fuel pump 3. Because water can not permeate the porous membrane filter 6 but fuel can be permeated therethrough, moisture is removed from fuel. Accumulated water is drained from a drain 7. This membrane filter may be interposed between the tank 1 and the usual filter 2 as an independent filter.

Title: Process scheduling system and multiprocessor system
Inventor: NAKAMURA TOMOAKI
IPC: G06F15/16
Filed: 1989-03-13
Abstract: PURPOSE:To execute the processes via the prescribed processors respectively by obtaining a system where a process scheduler actuates a selected process to be executed next via a processor designated by the processor allocation information on the processes and by reference to a process control table. CONSTITUTION:The processor identifiers 321-2 of a processor 2 is set at 1 and therefore the process 2 is executed by a processor P1. A process 1 can be executed by the processors except a processor P2 since the processor identifier 321-1 of the process 1 is set at 2. The idle processors are limited to the processors P2 and P3 and therefore the process 1 is executed by the processor P3. The processor identifier 321-3 of a process 3 is set at 0 and therefore the process 3 can be executed by any processor. In this case, the idle processor 2 is used. As a result, the processes can be executed by the prescribed processors respectively even in a uniform multiprocessor system.

Title: Heat resistant and wear resistant damper
Inventor: YAMASHITA HAJIME
IPC: F24F13/14
Filed: 1987-03-17
Abstract: PURPOSE:To make it possible to regulate a high temperature gas containing dust for long periods of time by covering a surface of a damper wing body on an upstream side of a gas flow with a wear resistant plate of an alumina- zirconia material. CONSTITUTION:A groove 23 is arranged on a surface of a metallic damper body 21 on an upstream side of a gas flow. A wear resistant plate 22 of an alumina-zirconia material with its back side formed with a raised portion is fitted to the groove 23 of the damper wing body 21. This makes the mounting of the wear resistant plate 22 easy and eliminates cracks due to repetition of high and low temperatures. Since alumina-zirconia reacts little with dust and has excellent heat and shock resistances, the life of the damper can be considerably extended.

Title: Magnetic sensor and manufacture thereof
Inventor: SUKIGARA HIDENORI
IPC: H01L43/08
Filed: 1989-03-13
Abstract: PURPOSE:To simplify manufacturing steps and to improve reliability by so forming the surface of protective resin in an arcuate state that the thickness of a part corresponding to a sensor is thinner than that of a part not corresponding to the sensor. CONSTITUTION:The surface 7a of a protective resin 7 is formed in an arcuate state. This arcuate state is so formed that the thickness of the part corresponding to a sensor 3 is thinner than that of a part not corresponding to the sensor 3. Accordingly, a magnetic sensor containing electrodes 4 and a lead frame 5 can be simultaneously sealed entirely with the resin 7. The resin of the sensor 3 is the sealing resin of the same material, and both can be simultaneously molded to eliminate a gap between the resins, thereby preventing a trouble due to invasion of moisture, impurities, etc. Thus, an accurate magnetic sensor having low cost and high reliability can be obtained by a relatively simple method.
